rlhis invention relates tojtent Vsupporting means and pertains particularly to a collapsible frame designed primarily for use in connection with tents ofk pyramidal formation.

The primary object of this inventionis to provide a supporting structure which will maintain the tent canvas in the proper position, eliminating the usual center pole which is usually in the way and which it is desirable to remove from the tent structure.

The invention broadly contemplates the.

provision of a plurality of poles which are designed to beyarranged in substantially vertical positionagainst the inner face of the tent wall, each pole carrying at its upper end an arm, which arms are attached to a center block member, which in turn supports an upright shaft designed to engage the central.`

A. further ob'ect of the invention is to proj vide a tent frame of Vstrong and durable construction and of a character which will enable one to readily raise the same to position.

The invention Willbe best understood from a consideration of the following detailed description taken in connection with the accom- 4 panying drawing forming part ofthe speci- 'v lIication and with the understanding, however, that the invention is not conned to any strict conformity with the showing of the drawing, but may be changed or modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.`

In the drawing- Figure 1 is a view in side elevation of the tent frame, with one pole removed,

Fig. 2 is a top plan View of a portion` of the frame,

Fig. 3 is a view of the'upper part of the 'frame partly folded. y c

Referring to the drawing in detail, wherein like numerals of reference indicate Hcorresponding parts throughout the several views,

the numeral 1 indicates the frame poles, each .of which is pointed at its lower endv as indicated at 2 and each ofthe poles carries ad- Jacent thelower end and uponthe outer side thereofa downturned hook member 3 to which a suitable eyelet ofthe tent canvas may be attachedfto hold the canvas in taut condition over the frame." Each ofthe poleslalso PATENT oEFlcE carries at yits lowerend astep 4 which is proyvided to facilitate the erection of the framed by the operatorplacing his footthereon and forclng downwardly to cause the pointed for'- ward end ofthe pole to penetrate the ground.

The pointed ends 2 of `the poles are iron. capped to fur-ther facilitate their extension into the ground andto protect the pole body during the insertion ofthe same.

At the upper end eachl of the poles has hmgedlyk attached thereto as at 5, an arm member 6. These arms are designedto be*y raisedto aposition substantiallyat right angles to their respective poles and so' held by a hinged. brace member 7 which spans the 1 corner .thus formed between the arm and,r

pole. The arms have the faces of their outer `ends obliquely angled to' conform to the complementarily jacent pole.V

angled abutting ends of the ad- Eachof the arms 6 is hingedly attached'as. F

Vat`8 to a central block member 9 which, when the frame is set up, assumes a position upon the longitudinal center thereof. In the present instance, four poles are shown, in which ca se thefarms 6 are connected to each of four, l

equi-distantly spaced points about the block 9. It is, of course to be understood that a greater or lesser number of arms and poles i may. be employed Without' departing from the spirit of the invention.

The blockfmember has a threaded aperture formed through the central portion thereof in which the threaded end of an upright stub pole 10 isk designed to engage, the upper end of this pole being provided with a pin member 1l for extension through the usual central eyelet formed in the peak vof` l i tents of the character in connection ywith which the present frame is designed to bek used. This stub pole provides a convenient i imam means for tightening up the tent body when a such procedure is necessary.

From the foregoing description, it Will be readily seen that the present tent frame is designed to be quickly set up and when in set up position will support a tent canvas better than the usual center pole, Without the disadvantage of having a pole or other struc- 'ture'in the center ofthe tent. By providin the lower edge of the tent canvas with suitable eyelets for `engagement over the hooks, the Wall thereof Will be held tightly in place upon the frame, thus avoiding the H necessity of using a pluralityofguy ropes.

Having thus described my invention, What` LA tent frame structure comprising ai y urality of poles designed to be arranged y y 1n substantially upright position, each of said poles havinvr its upper end angled to provide i an oblique ace, a plurality of arms each havy one end angled to provide an oblique face `adapted to abuta complementarily formed ,ace of a pole `Whenthe frame is set up to old the arms lin a fixed position, hinge-elements connecting said arms with the adjacent poles, collapsible brace elements connect` lng each of the arms with the adjacent pole, a

"central block member having the other ends of la said arms pivotallyconnected thereto, and a i center stub pole threadably extended through l an oblique face, a plurality of arms each havy said central member.

2. Ar tent frame structure comprising a lurality of poles designed to be arranged 1n substantially upright position each of said poles having its upper end angled to provide ingone endangled to provide an oblique face adapted to abut a complementarily formed face of a pole when the frame is set up to hold collapsible brace elements connecting each of the arms with the adjacent pole, a central block member having the other ends of said arms arranged to abut against side faces thereof, hinge members upon the upper faces of said arms and said central member piv lot-ally securing the arms thereto to permit signature.
